Automotive 0.5A Variable Output

LDO Regulator

BDxxHA5MEFJ-M

●General Description

BDxxHA5MEFJ-M is a LDO regulator with output current 0.5A. The output accuracy is ±1% of output voltage. With external

resistance, it is available to set the output voltage at random (from 1.5V to 7.0V).It has package type: HTSOP-J8. Over

current protection (for protecting the IC destruction by output short circuit), circuit current ON/OFF switch (for setting the

circuit 0μA at shutdown mode), and thermal shutdown circuit (for protecting IC from heat destruction by over load condition)

are all built in. It is usable for ceramic capacitor and enables to improve smaller set and long-life.

Most of the heat loss that occurs in the BDxxHA5MEFJ-M is generated from the output Pch FET. Power loss is determined

by the total V_CC-V_Ovoltage and output current. Be sure to confirm the system input and output voltage and the output

current conditions in relation to the heat dissipation characteristics of the V_CCand V_Oin the design. Bearing in mind that

heat dissipation may vary substantially depending on the substrate employed (due to the power package incorporated in

the BDxxHA5MEFJ-M make certain to factor conditions such as substrate size into the thermal design.

Power consumption[W] = Input voltage (V_CC) - Output voltage (V_O) ×I_O(Ave)

Example) Where V_CC=5.0V, V_O=3.3V, I_O(Ave) = 0.1A,

Power consumption[W] = 5.0V - 3.3V ×0.1A

=0.17W

●Input-to-Output Capacitor

It is recommended that a capacitor is placed nearby pin between Input pin and GND, output pin and GND.

A capacitor, between input pin and GND, is valid when the power supply impedance is high or drawing is long. Also as for

a capacitor, between output pin and GND, the greater the capacity, more sustainable the line regulation and it makes

improvement of characteristics by load change. However, please check by mounted on a board for the actual application.

Ceramic capacitor usually has difference, thermal characteristics and series bias characteristics, and moreover capacity

decreases gradually by using conditions.

For more detail, please be sure to inquire the manufacturer, and select the best ceramic capacitor.

●Equivalent Series Resistance ESR (ceramic capacitor etc.)

Please attach an anti-oscillation capacitor between V_Oand

GND. Capacitor usually has ESR(Equivalent Series

Resistance), and operates stable in ESR-I_Orange, showed

right. Generally, ESR of ceramic, tantalum and electronic

capacitor etc. is different for each, so please be sure to check

a capacitor which is going to use, and use it inside the stable

operating region, showed right. Then, please evaluate for the

actual application.

･Input capacitor C_INof V_CC(V_IN) should be placed very close to V_CC(V_IN) pin as possible, and used broad wiring pattern.

Output capacitor C_OUTalso should be placed close to IC pin as possible. In case connected to inner layer GND plane,

please use several through hole.

・FB pin has comparatively high impedance, and is apt to be effected by noise, so floating capacity should be minimum as

possible. Please be careful in wiring drawing

・Please take GND pattern space widely, and design layout to be able to increase radiation efficiency.

・For output voltage setting

Output voltage can be set by FB pin voltage（0.800V typ.）and external resistance R1, R2.

（The use of resistors with R1+R2=1k to 90kΩ is recommended）

●Operational Notes

(1). Absolute maximum ratings

An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc.,

can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open

circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection

devices, such as fuses.

(2). Connecting the power supply connector backward

Connecting of the power supply in reverse polarity can damage IC. Take precautions when connecting the power

supply lines. An external direction diode can be added.

(3). Power supply lines

Design PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and supply

line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply

terminals to ICs, connect a capacitor between the power supply and the GND terminal. When applying electrolytic

capacitors in the circuit, not that capacitance characteristic values are reduced at low temperatures.

(4). GND voltage

The potential of GND pin must be minimum potential in all operating conditions.

(5). Thermal design

Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating

conditions.

(6). Inter-pin shorts and mounting errors

Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any

connection error or if pins are shorted together.

(7). Actions in strong electromagnetic field

Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to

malfunction.

(8). ASO

When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO.

(9). Thermal shutdown circuit

The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is

designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its

operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the

operation of this circuit is assumed.

(10). Testing on application boards

When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to

stress. Always discharge capacitors after each process or step. Always turn the IC’s power supply off before

connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly

steps as an antistatic measure. Use similar precaution when transporting or storing the IC.

(11). Regarding input pin of the IC

This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them

isolated.

P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic

diode or transistor. For example, the relation between each potential is as follows:

When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.

When GND > Pin B, the P-N junction operates as a parasitic transistor.

Parasitic diodes can occur inevitable in the structure of the IC.

The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical

damage. Accordingly, methods by which parasitic diodes operate, such as applying a voltage that is lower than the

GND(P substrate) voltage to an input pin, should not be used.

(12). Ground Wiring Pattern.

When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns,

placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage

variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to

change the GND wiring pattern of any external components, either.
